LONDON (AP) — To music producer Mark Ronson, the Olympics resound with thwacks and grunts, screeches and thumps.

The three-time Grammy winner described Thursday how he has been working with Olympic hopefuls from five countries to create a soundtrack for the London 2012 Games — an anthem that fuses sounds from training with the beat of music.

Ronson, who worked with the late singer Amy Winehouse, recorded athletes as they trained, sometimes attaching microphones to legs, chests and arms. He also placed them on running tracks and archery targets — often getting sound not possible during the games because they would interfere with competition.

He recorded the bounce of a table tennis ball and the thwack of an arrow being released from an archer’s bow.
